SPECIFICATION forming part of Letters Patent N 0. 735,750, dated August 11, 1903.

Application filed April 13,1903.

T ctZZ whom it may concern:

porting the same.

Be it known that we, EDGAR. .T. GOLDSMITH and HUGO GOLDSMITH, citizens of the U nited States, and residents of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Supporting Mechanism for Striking-Bags, of which the following is a specification.

Among the various objects of our inven tion there should at this point in the specification be noted, first, a remarkable portabilityofstructure; secondly, great compactness of the parts; thirdly, a structure whose parts at will are readily separated and again readily united; fourthly, horizontal adj ust-ability of the structure which immediately supports the bag; fifthly, verticaladjustability of the same structure; sixthly, adjustability for varying the length of the travel of the bag; seventhly, a convenient means whenthe cord which supports the bagis lengthened or shortened for enabling the bag to strike its abutment centrally and in a desired position.

Other objects additional to these, someof them consequential thereto, will be herein after apparent.

The several features of our invention and the several features resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the accompanying drawings, making a part of this specification, and in which similar letters of reference indicate corresponding parts, Figure 1 represents in perspective a view of the mechanism immediately connected with the bag and the arm and part of the means of the preferred means for sup- Fig. 2 represents a top plan View of mechanism illustrating our' invention, excepting means for supporting the upright or vertical shaft on which the supporting-bracket is pivoted.

Fig. 4 represents a top View of the preferred means for supporting the said vertical shaft. Fig; 5 represents a front elevation of the device shown in Fig. 4. Fig. 6 represents in vertitends.

In the Serial No. 152,401. (No model.)

cal central section a single means for upholding the horizontal shaft which supports the striking-abutment and the striking-bag and which allows the horizontal shaft to be moved in a horizontal plane. Fig. 7 is a View in perspective,showing the striking-bag and its supporting mechanism upheld by the frame ofa door.

We will now proceed to describe our invention in detail.

A indicates the striking-bag; B, the cord which supports it. This cord is connected to the bag in any suitable manner.

O indicates the abutment, against the outer side of which the bag strikes. The abutment is provided with a downward extension D, whose lower end is of much less diameter than the diameter of'the abutment O. For the purpose of economizing metal and diminishing unnecessary weight the upper portion of this extension is also of much less diameter than that of the abutment. The lower end of the abutment has a vertical passage D through which the cord B ex- To allow the cord to easily oscillate as the bag is moved back and forth, the passage enlarges in a tapered form, making an inclined annular side D Above this passage the vertical opening D enlarges, forming the chamber D havingthe annular shoulder D In order to more readily reach the rope immediately above the shoulder D, we

provide an opening D extending through I the wall of the extension and to the chamber D Thus when the cord of the bag A is. to be connected to. the part D the upper end of the rope is passed up through the passage D and knotted at a suitable point of it above the shoulder D and then dropped, so that the knot B rests upon the shoulder D The lower edge D of the passage D is rounded,

As it is desirable to shorten and lengthen tle cord B below the extension D, so as to vary at will the length of the arc in which the bag travels and the consequent number of the oscillations of the bag, the side of the abutment is made correspondingly long from top to bottom. Thus the preferred width vertically of this side 0 is about four-inches. Such an extension enables the abutment G to duly receive the impact of the side of the bag when the latter is struck and swings up. To best accomplish this, the plane of the inclination of the side C when extended down will just meet the point or edge D. This accommodationviz., this extended fiat side 0 inclined, as shownofi?ers special advantages over the ordinary ring-abutment,whose height is very little and whose outer surface is an arc of a circle. In the latter instance there is only one length of cord, with which the bag will strike the ring exactly at its side center-that is, at the end of the transverse axis of the bag and at right angles to that axis of the bag which is the extension of the axis of the cord; but with an abutment of the shape which we present during every variation of the length of the cord from the longest to the shortest condition of length (extension) the center of the bag will strike the abutment in the same manner and the said transverse axis of the bag will be at right angles to the up and down inclination of the side 0 Under these conditions we are not only able to provide a very varied length of swing for the bag, but also to have the bag in every instance strike correctly. In consequence the bag will not be wrenched or strained; but if it is so strained its connection with the cord is strained when it strikes the abutment in any other manner than that last described. We are therefore by this feature of our invention enabled to increase the variation in the length of the cord of the bag and at the same time prolong the duration of the bag and its efficiency and also accelerate its rebound by causing it to strike at the point of its largest diameter.

It is to be understood that the primary object in varying the length of the swing of the bag is to vary the speed of its movement. The shorter the arc the greater the speed, and vice versa.

We uphold the abutment C by a suitable support. A preferred one consists of the single arm E, provided with branches E E These branches E E may be separable from the arm E and suitably fastened thereto. One

mode of such separable connection is illusthe abutment C, and the foot of the other branch E is secured to an opposite portion of the abutment, substantially as shown. The branches may be integral with the arm E. Such a condition of construction is shown in Figs. 2, 3, and 7. \Vhen preferred, the branches may be shorter and more centrally connected to the abutment, substantially as shown, by the set of inner branches at E There the branches E E are respectively connected at E E to a part of the abutment adapted to receive them. It is to be understood that when the shorter branches are used the longer branches will be omitted, and vice versa. In any case, no matter how connected to the abutment, the arm E extends back and is duly supported in a bracket or brackets which admit of it being moved horizontally from the right to theleft,or vice versa. A simple mode of doing this is illustrated in Fig.6. Herethearm Ehasavcrticalportion 11*, having shoulders K A bracket M, screwed or otherwise secured to the woodwork at the part or parts M receives the part H of the bracket. A set-screw N of the bracket M enables the arm E to be set after being located at the correct part of the horizontal arc in which it moves; but the preferred mode of adjustably connecting the arm to the supporting woodwork, &c., is as follows: There are two brackets M M. The vertical shaft H is received in them. The bracket-arm E by means of a sleeve or bearing E embraces the shaft H and to admit of readilybeing secured thereto or detached therefrom and at a desired height on the shaft H. This sleeve or hearing E which embraces the bar, has a securing bolt or bolts E. Although the lower end of the shaft H may be diminished and have shoulders K and be set in a bracket, as exemplified in Fig. 6, we preferably allow the shaft H of full size to be within the lower bracket and uphold the shaft H by a collar K, fixed on the shaft at the desired point along the vertical length of the latter. The bracket K will rest and turn upon the lower bracket. Where the shaft H is long and of greater length than the distance between the bottom of the lower bracket and the top of the upper bracket as placed, the shaft carrying the arm E fixed to it can be adjusted vertically by changing the position of the collar K thereon, and thus the arm E will be raised or lowered without disturbing the bolts E E"; otherwise to lower or raise the arm E for adjusting the frame and bag vertically to suit the different heights of the individuals using same the bolts E E must be loosened and after such adjustment then be tightened. The preferred construction of the means for supporting the arm where two brackets M M are employed is wellillustrated in Fig. 7. So far as the construction of the sleeve or hearing E relative to the arm E is concerned the sleeve may receive the end of the arm, as in Fig. 1, or be integral therewith, as illustrated in Fig. 2.

The mechanism is set up and operated as follows: The bracket or brackets M are affixed to the woodwork or equivalent support. The shaft H is located in the bracket or brackets M. When the constructions shown in Fig. 2 are present, the collar K and the arm or shaft E are set at desired points on the shaft or upright II. The abutment is then moved out to the desired position, the arm E moving with the shaft H to accommodate this movement. Then the set-screws Not the bracket-arms are tightened and the shaft fixed in position. Thus the abutment will be made stationary. Where the device shown in Fig. 6 is used, the set-screw N is tightened after the abutment has been putinto position. The extent of the swing of the bag and its consequent rapidity of movement will be regulated by the length of the cord between the bag and the extension D, as aforementioned.

Our device is very portable and convenient. Obviously it accomplishes all of the objects which it is designed to do and as enumerated in the opening portion of this specification.

Our mechanism can be readily connected to the side of a door-frame of a closet or other compartment. When it is to be used, the arm E, with abutment C, can be swung out and set. It is then ready and can be used so long as desired. When not in use, it can be swung back and the door closed. As the abutment and arm E can be, so to speak, moved against the door or wall, so as to lie close to it and out of the way when not in use, it also offers in this way much of advantage to young men and others possessed of a limited amount of room-space. One illustration of such application is seen in Fig. 7.

When we mention the branches E ,we mean subarms, and by the term subarms we mean these branches.
